Ore no Imouto ga Konna ni Kawaii Wake ga Nai series

[JedSomax]

My english is not good. But I need some help.

So here i go. Well, I started to playing Ore no Imouto ga Konna ni Kawaii Wake ga Nai Portable ga Tsuzuku Wake ga Nai and i cannot save with the normal way, not with savestate. It says that I need no have a memory card. And Im searching a lot to find a way to create one, because i know that i can. But they're for android or says others ways for others games.

Please help as faster that you all can I want to keep playing

Btw, I play in PC

EDIT: Now I know what to do. For anyone who in the future would have the same problem just dont use savestates and open the game again.
